Abstract: This paper presented a kind of whole substation testing method. This method was based on the integrated automation system of substation, combined with the characteristics of the main wiring. The excitation point was placed in the entry lines and low-voltage bus bar of substation, and the current and voltage signals at secondary side were collected in terminals of control device and electric energy acquisition device in distribution room and relay room to judge the wiring connection situation of secondary circuit. Introduction was made to the test flow and the key technology. The field test results indicate that this method has enhanced the efficiency and accuracy of the current and voltage transformer secondary circuit of the substation.
Key words: current and voltage secondary circuit; whole substation test method; wireless communication
